Urban Oasis is a term used to describe an area in an urban environment that provides a peaceful and calming atmosphere. A PARK is a public outdoor space, usually with trees and grass, where people can relax and enjoy nature. A rooftop garden is an area on the roof of a building that has been landscaped with plants, trees, and other vegetation. Both parks and rooftop gardens provide a much-needed oasis in the midst of an urban environment.
